NTTR STATES FREDERICK IIARVEY RAPLEY, OF CHICAGO, ILLINOIS, ASSIGN OR TO IHE FOX SOLID PRESSED STEEL COMPANY, OF SAME PLACE.

UNDERFRAIVIE FOR CARS.

SPECIFICATION forming part of Letters Patent 1\T o. 585,405, dated June 29, 189'?.

Application tied April 10,1896.

To all whom it may concern.-

Beit known that I, FREDERICK HARVEY RAPLEY, of. Chicago, Cool; county, Illinois, have invented new and useful Improvements in Underframes for Cars, of which the following is a full and complete description.

This invention relates to railway-cars and it consists in an improved form of steel underframe or that portion of a car upon which the flooring is laid and which supports the body of the car upon its trucks.

My improved form of underframe combines maximum strength with minimum weight of metal, together With novel and desirable methods of securin g together the various parts thereof.

My improvements are fully illustrated in the accompanying drawings, in which- Figure l represents a plan of the underframe with part of the draft-gear; Fig. 2, an elevation of the same, showing portions of the truck and car brace-timbers in dotted lines. Fig. 3 is a part sectional plan of the underframe; Fig. 4t, a sectional elevation of the same. Fig. 5 is a half end elevation of the frame; and Fig. 6 is a sectional elevation 011 the line :v w, Fig. 3.

The longitudinal sills a4, a5, and F of the improved underframe are preferably constructed of rolled steel and the end sills a of pressed steel. The body-bolster beams G and the transverse sills d2 d3 are preferably formed of pressed steel. The mode of securing the draft-gear to the central longitudinal sills F is illustrated in Figs. 3 and 4, the cheek-plates or draft-sills ff being riveted thereto. The transverse sills a2 0,3 are provided with longitudinal flanges h', whereby they are secured to the longitudinal sills. The truck-sills are each composed of two parts a2, secured to the side sills by their flanges and by the horizontal plates B B, riveted thereto, and to the central longitudinal sill F by the horizontal plates b2. The corners C of the underframe are secured together and to the ends of the bolsterbeams by special gussets g2. The central sills are secured at their ends by angle-plates f2', which are bolted through the buffer-beams Serial No. 586,911. (No model.)

and also riveted to the sides of the central longitudinal sills, as at f3. Vertical bolts g4 are also used to secure the end plates to the buffer-beams. The intermediate longitudinal sills are flanged and riveted to the end sills and bolster-beam G, as at g. The base and center plates J, truck-bolster I-I, draw-bar guide g3, and side bearing K are of ordinary construction.

The partial views of the various parts given in the drawings herewith illustrate those parts not shown, Which are simply duplicates of those represented.

In other designs for metal underframes for cars with which I am acquainted diagonal braces have been used for securing together the various parts of the frame and imparting additional strength and rigidity to it. The gusset-plates of my improved frame, however, constitute a more simple and effective way of attaining these ends, are more readily secured to the frame, and occupy less space than do other similar devices.

In the practice of my invention I am not of course limited to the use of bolts or rivets in securing together the various parts of the underframe, nor as to any particular type of car, as my improved frame may be applied to any of the several classes of railway-cars in common use. It is, however, specially adapted to iron or steel cars of any well-known type.

Having thus described my invention, I claim In an underframe for cars, the combination of the end sills ci', the transverse sills 0.2 a3, the corner gusset-plates g2, the intermediate longitudinal sills a5, provided with anged ends gfor securing same to the end and transverse sills,the horizontal octagonal plates b2 b4, and the hexagonal side plates B B, substantially as specified.

In testimony whereof I have signed my name to this specication in the presence of tWo subscribing witnesses.

FREDERICK HARVEY RAPLEI.
